They're pretty great with anything except the guy passing his car off as "occasional use" when it's really his summer DD. They were even fine with me driving my car all the way down to North Carolina for pleasure use.

A recurring sticking point I've heard is don't take your car out to shopping centers/mall they don't like that and track days are out the window. I had to sign a form when I got my policy stating I wouldn't track my car IIRC.
